Feb. 11, 1935, No. 4352. [Class 27] In a coin collector for telephone services in which the act of inserting a coin sets a coin holder for holding the coin in a position of suspense from which it is either cashed in or out, according as the call is effective or not, the coin A comes to rest on a lateral projection of a balance beam B and is retained in a position of suspense by two studs C projecting from a rock arm D pivoted at E, a roller D<1> at the top of the arm D engaging the bottom of a V- notch in a cam lever F pivoted at F<1>. During insertion, the coin engages and rocks a lever M to rock the lever F so that the roller D<1> becomes centred in the notch. The lever F is held in its raised position by a roller F<3> carried by a spring engaging the bottom of two notches in a plate F<2> on the lever. The lever F also controls contacts N, such as for removing a short circuit from the dial and short-circuiting the transmitter. If the call is effective, the coin is cashed in by depressing the lever F by a plunger G, the lower portion of the rock arm D being pulled to the left by a spring H. For refunding, the replacement of the receiver on its hook rocks a lever K which stresses a plate spring L on the rock arm D and moves the upper end of this to the left, disengaging the roller F<3> and depressing the cam lever. A clockwork escapement O with a vertical arm O<1> is disposed below the rock arm D which carries a pivoted pawl P to engage the arm O<1> when the balance beam B is depressed by a coin. When the coin is being refunded, the pawl P winds up the clockwork which actuates contacts Q for cutting the line for a predetermined period.

Abstract: 1508918 Analogue-to-digital conversion COMMISSARIAT A L'ENERGIE ATOMIQUE 5 Feb 1976 [18 Feb 1975] 04616/76 Heading H3H Digital coordinates (n, m) of points on a shortlived curve x(t) displayed on an oscilloscope screen 4 are derived by transferring the curve by means of a T.V. camera 10 to a storage target which is scanned in a raster whose lines run perpendicular to the time axis of the curve, a line address n being generated by a line counter 44 and a position-inline address m being derived by counting clock pulses in a counter 42, n and m being interleaved by a multiplexer 50, buffered by a series of registers 16 and transferred to a computer memory 18. Position-in-line coding is done by comparing the signal from the scanned storage target with a plurality of thresholds in geometric progression (80-88), Fig. 7 (not shown) and transferring the count reached by a binary counter (108, 110, 112), Fig. 9 (not shown), counting clock pulses from zero at the start of each line to a second counter (114, 116, 118) at the next clock pulse after the time when the highest threshold to be exceeded is exceeded. The transfer includes a doubling shift and clock pulses are added to the transferred count until the next clock pulse after the time when said highest threshold is no longer exceeded, whereupon the count attained is read out with a halving shift, thereby obtaining the code m for the midpoint of x(t) in the event of a broad trace. The line counter 44 is reset to zero by the frame synchronizing pulses and for an interleaved raster is incremented by two for each line of any one frame, alternate frames being offset by unity. Phase-displaced clock pulses H 1  and H 1 <SP>1</SP> are generated by a clock 36, line frequency being obtained by a divider 38. A monitor screen 22 may be provided to facilitate adjustment.
